The strain called bird flu is an influenza A virus and gets its name because wild birds such as gulls, ducks geese and other waterfowl act as hosts for the virus.
Perhaps the most notable is the so-called “Spanish flu” of 1918–1919, when the Centers for Disease Control and Prevention (CDC) estimates “an avian-like H1N1 virus” killed 50 million ...
Avian influenza, also known as avian flu or bird flu, is a disease caused by the influenza A virus, which primarily affects birds but can sometimes affect mammals including humans. [1] Wild aquatic birds are the primary host of the influenza A virus, which is enzootic (continually present) in many bird populations.
The females give birth to a single baby; twins have been recorded once at the Drill Rehab & Breeding Center in Nigeria. [4] The average longevity in captivity is 28 years. The diet is primarily frugivorous, taking a wide range of fruit, but they also eat herbs, roots, eggs, insects, and small mammals on occasion. [4] [6]
A bird-adapted strain of H5N1, called HPAI A(H5N1) for "highly pathogenic avian influenza virus of type A of subtype H5N1", is the causative agent of H5N1 flu. HPAI A(H5N1) is considered an avian disease, although there is some evidence of limited human-to-human transmission of the virus. [2] A risk factor for contracting the virus is handling ...
So far, bird flu outbreaks in the U.S. have been from a strain of highly pathogenic avian influenza (HPAI) called H5N1. That strain has been responsible for all the egg shortages and infections in ...
Influenza A virus subtype H5N1 (A/H5N1) is a subtype of the influenza A virus, which causes the disease avian influenza (often referred to as "bird flu"). It is enzootic (maintained in the population) in many bird populations, and also panzootic (affecting animals of many species over a wide area). [1]
Bird flu is a scary illness with a high mortality rate. But so far, infections in the U.S. have been relatively mild—until now. A patient in Louisiana has been hospitalized with a severe case of ...
